Description

Technical Field

[0001] The utility model relates to the technical field of alloy saw blade production auxiliary equipment, in particular to a hard alloy saw blade process turnover box. Background Art

[0002] The manufacturing process for carbide saw blades typically involves sandblasting, polishing, grinding, and rust prevention. Since carbide saw blades are mass-produced, each process inevitably produces a certain number of semi-finished products. Once the required quantity is reached, the blades are moved to the next process, and the time it takes for each process to complete can range from several hours to several days. When humidity exceeds 50%, rust can form on the blade surface within just one or two hours. The resulting waste caused by rust is significant, presenting a significant challenge for every carbide saw blade manufacturer. The typical solution to rusted saw blades is re-polishing. This re-polishing process results in significant losses, both financial and personal losses, and, crucially, increases the blade's end jump, compromising quality.

[0003] At present, the tooling for placing saw blades in the process room is generally a special trolley. A production line that is dozens of meters long for one process has only one or two trolleys.

[0004] 1. Before the specified number of saw blades is reached for each process, they must be placed on a workbench next to each machine, with the blades level and stacked. Once the required number is reached, a trolley is brought in and a few blades are placed one at a time, with the center holes of the blades threaded onto the trolley's positioning shaft. Without rust prevention measures, rust can easily result and waste occurs.

[0005] 2. In addition, the gear grinding process requires the use of a dedicated grinding fluid. After the saw blades are ground, they are coated with grinding fluid. When stacked on the workbench, the grinding fluid on the saw blades will always flow onto the workbench and onto the floor. Saw blades on tooling trolleys will also drip grinding fluid onto the workshop floor as the trolley passes by. This creates difficulties for environmental protection and civilized production.

[0006] 3. The number of saw blades on the tooling trolley had to be counted repeatedly. Each process needed to count the semi-finished products when receiving them to clarify responsibilities, which was quite tedious.

[0007] An existing patent application, application number 201220125493.8, is titled "A Portable Saw Blade Turnover Box." It discloses a box comprising a base, connecting posts, and a lid. The base, connecting posts, and lid are independent components connected by connectors. The connecting posts comprise multiple adjustable-length columns. The connecting posts are plugged into the base and lid, respectively. This patent application is open-ended and does not address the issue of carbide saw blade rust in high humidity.

[0036] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work shall fall within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figure 1-12 As shown,

[0039] A carbide saw blade process turnover box, used for transporting carbide saw blades between process steps, comprises a water tank 1, a saw blade holder 2 mounted at the bottom center of the water tank 1, a positioning shaft 3 mounted at the center of the saw blade holder 2, and a handle 4 mounted on the positioning shaft 3. A carbide saw blade 5, with its center hole passing through the positioning shaft 3, is placed on the saw blade holder 2. The water tank 1 contains rust-proof water 6 to prevent the saw blade from rusting. The water tank is filled with rust-proof water 6, immersing the saw blade in the rust-proof water 6 to achieve its rust-proofing function. When the air humidity is low, the saw blade holder 2, positioning shaft 3, and handle 4 can be used independently, without being placed in the rust-proof water 6.

[0040] The water tank 1 is a hollow inverted square pyramid with an open top, a large top and a small bottom, and a square bottom.

[0041] The four corners of the bottom surface of the water tank 1 are each provided with an L-shaped grounding seat 42; normally, the grounding seat 42 is in contact with the workbench, which can reduce the wear of the water tank 1, extend the service life, and at the same time increase the strength of the bottom surface of the water tank 1.

[0042] The top of the water tank 1 includes four sides, with a pair of opposing sides having lifting lugs 41. A weight-bearing boss 43 for mounting the saw blade holder 2 is located at the center of the bottom of the water tank 1. The weight-bearing boss 43 is shaped like a truncated cone, smaller at the top and larger at the bottom. The top of the weight-bearing boss 43 has a diameter of D2 and a center hole with a diameter of D1.

[0043] The detailed structure of the water tank 1 is:

[0044] like Figure 10-12As shown, the water trough 1 is generally square and bucket-shaped, made of injection-molded engineering plastic. Its horizontal cross-section is square, with a lower side length of L2. The outer diameter of the carbide saw blade 5 is D; D+20≤L2≤D+100. A circular, upper- and lower-larged, weight-bearing boss 43 is positioned upward from the bottom of the water trough 1. The upper diameter of the boss 43 is D2. The height of the boss 42 is H7, with a range of 10mm≤H7≤20mm. A conical cavity, larger at the top and smaller at the bottom, is located at the center of the boss 43 to accommodate the lower protrusion of the saw blade holder 2. The inner diameter of the cavity is D1, and the depth of the cavity is H9 = H7.

[0045] Two reinforcing ribs are provided on the bottom of the water tank 1. One is circular with a diameter of D3, 0.5*L2≤D3≤0.7*L2; the other reinforcing rib is a grounding seat 42 provided on the inner side of the four corners of the bottom of the water tank 1. The grounding seat 42 is a right-angle structure with a side length of L4, 30mm≤L4≤80mm; the width of the reinforcing rib is B1, 5mm≤B1≤15mm; the height of all reinforcing ribs is H 10 ,5mm≤H 10 ≤10mm; set appropriate draft angle on all rib sides.

[0046] The four side walls of the water tank 1 are provided with an inclination ε, 10°≤ε≤15°, and the inclination is provided for easy demoulding during production. The four side walls are provided with a thickness δ, 3mm≤δ≤7mm.

[0047] The length of the lifting ear 41 is 150mm-200mm, and the height of the lifting ear 41 is H 11 ,30mm≤H 11 ≤60mm; easy to hold the lifting lug by hand.

[0048] The saw blade seat 2 is in the shape of an inverted frustum of a cone; the diameter of the bottom end of the saw blade seat 2 is D3; D3 is larger than D2; a guide seat 23 is provided on the bottom surface of the saw blade seat 2; the guide seat 23 is inserted into the center hole.

[0049] The bottom surface of the saw blade seat 2 is evenly distributed with legs 21; the legs 21 are arc-shaped; the load-bearing boss 43 is sleeved in the legs 21; the inner diameter of the legs 21 is larger than D2;

[0050] A nut 22 is embedded in the center of the saw blade seat 2 ; the positioning shaft 3 is threadedly connected to the nut 22 .

[0051] The detailed structure of the saw blade seat 2 is as follows: Figure 4-6 ,

[0052] The saw blade seat 2 is a component that bears the weight of the saw blade. The main body of the saw blade seat 2 is made of engineering plastic injection molding. A nut 22 is embedded in the center. The axis of the nut 22 coincides with the axis of the saw blade seat 2. Figure 5The saw blade seat 2 is circular in the horizontal plane, and a hole is provided on the saw blade seat 22 around the top of the nut 22, and the hole diameter is D4, which is larger than the threaded hole diameter of the nut 22 and smaller than the diameter formed by the outer contour of the nut 22;

[0053] The nut 22 is M10 or larger, and the distance between the upper surface of the nut 22 and the upper surface of the saw blade holder 2 is greater than or equal to 4 mm. Three legs 22 are evenly distributed at the lower end of the saw blade holder 2. Each leg 22 has a central angle of θ, with a range of 40° ≤ θ ≤ 60°. The radial and inner circumferential surfaces of the legs 21 are sloped to facilitate mold removal. The radial slope is θ1, with a range of 15° ≤ θ1 ≤ 25°.

The diameter of the center shaft is d3, with d-0.5≤d3≤d-0.25, where d is the diameter of the saw blade's center hole. The length of the center shaft is L3. L3 is determined by the mass of the saw blade and the thickness of the base. w is the mass of each saw blade in kg, with L3 ≤ (20 / w)*T1. T1 is the thickness of the saw blade. The threaded diameter at the lower end of the positioning shaft 3 is compatible with the nut 22 embedded in the saw blade holder 2.

[0056] The working process of this utility model is:

[0057] Place the saw blade seat 2 on the load-bearing boss 43 of the water tank 1, tighten the positioning shaft 3 on the nut 22, add anti-rust water 6 into the water tank 1, and place it on the workbench; put the semi-finished saw blade on the positioning shaft 3, and when the positioning shaft 3 is full of carbide saw blades 5, screw on the handle 4 to facilitate transportation of the entire stack.

[0058] Multiple sinks 1 are stacked in a staggered arrangement, with the sides with and without the handles 41 alternating. When the sinks 1 are stacked, the top surface of the load-bearing boss 43 of the lower sink 1 contacts the bottom surface of the upper sink 43, supporting the upper sink 1. A gap δ1 is maintained between the sides of the sinks 1, where 1≤δ1≤5.
